Does it? I thought sCO2 could operate at small temperature gradients. In fact, I thought sCO2 can work for industrial heat pumps.

- pfdietz 5y agoThe applications for nuclear under investigation involve temperatures of 550 C to 800 C. https://www.energy.gov/sco2-power-cycles/sco2-power-cycles-nuclear https://www.energy.gov/sco2-power-cycles/sco2-power-cycles-n... This chart shows temperatures for nuclear applications as low as 350 C, but that's still hotter than today's LWRs. https://www.energy.gov/sites/prod/files/2015/01/f19/NEACsCO2BraytonBrief.pdf https://www.energy.gov/sites/prod/files/2015/01/f19/NEACsCO2... This second pdf shows the problem: replacing steam means not just building sCO2 turbines, but doing all the incremental optimizations on them that steam turbines already have.
